No. If only governments were held responsible, do you imagine what mess we would have in international relations? So, communists took billions of loans. Who should pay them after the collapse of communism?

How about this:US government lends a lot of money to another country. There is a coup de etat and their government is overthrown. The old guys have been executed. The new guys in power say the US can kiss the loan goodbye. . Will you be happy about it as an American tax payer?

This means that if the US authorities demand the payment of the debt from a country despite its government, communist countries had to repay their debts even after the collapse of communism. Isn`t it obvious? :):)
